My invention relates to ilat Ahosiery frames having a needle bar divided in each section, and particularly to the drive of the central portion of the section.

My invention makes it possible, without resorting to bolting devices which are bothersome to operate, to eiect positive motion of the central portion in such a way that its needles can be adjusted so as to be exactly in line with those of the side portions. For this purpose I employ a slide which is adjustable parallel to the needle row and which drives the central portion of the section by means of an obliquely disposed rib. The stopping device is arranged on the carriage to be displaced and on the central portion of the section, so that the stops act transversely to the direction of motion of the central portion of the section. This arrangement is advantageous, since it insures greater accuracy of adjustment corresponding to the ratio of the transmission of motion due to the obliquely disposed rib than if the central portion of the section is to be moved towards stops secured to the machine frame. When used in connection with a slide having an oblique rib the known stopping devices would lead to very troublesome self-locking of the central portion of the section whereby the adjustment of the central portion would be rendered quite difficult. Since the bolting devices are dispensed with, the adjustment of the central portion according to the invention requires less time than in the known arrangements.

By way of example, o ne embodiment of the invention is illustrated in the accompanying drawing, in which Figures 1 and 2 are, respectively, a side view and plan of the central portion in operative position; and Figs. 3 and 4 are, respectively, a side view and plan of the central portion when-withdrawn.

Referring to the drawing, between the side portions 1 and 2 the central portion 3 with the lateral wings 4 and 5 of the section can be adjusted parallel to itself owing to the foot 6 which carries the central portion 3 with the wings 4 and 5 and which is displaceable on theinclined guide 'l transversely to the direction of the needle row 8, the guide 'l being rmly connected with the side portionsgl and 2 and moved up and down with them in known manner. In order to adjust the foot 6 with 'the requisite degree of accuracy on the guide 7, the latter is provided with a groove. The member 9 has a rib or guide 10 within range of the correlated foot 6 and is adjustable parallel to the needle row 8. 'Ihe rib 10 engages a companion guide or slot 11 in the underside of the foot 6 and is disposed, at a slight angle, obliquely to the direction of motion of the central portion 3, so that by a longitudinal displacement of the member 9 the central portion 3 with the foot 6 will be moved along 60 the guide 7. A front face of the guide 7 is provided with the stop screw 15 and the adjusting member 9 with a nose 16 which at the end of the adjusting motion hugs the screw 15 and thus limits the mo- 65 tion of the central portion. The screw 15 must be adjusted so that at the end of the motion of the member 9 the needles of the central portion will be in line with the -needles'8 of the side portions 1 and 2. 70

The displacement of the member 9 of each sec-l tion may take place either by hand or by means of a driving rod 17 which passes through the frame and carries a driver 18 within range of each section, which is displaceable on the rod 17. By means of a spring 20 supported by the adjusting ring 19 the driver 18 will be pressed against the adjusting ring 21 secured to the rod 17. A projection 22 of the driver 18 engages a recess of the noseA 16 `which is thus, during axial motion of the rod 17, driven until it meets the stop screw 15 whereby the central portion 3 is brought into' operative position in the manner described.

The rod 17 is disposed on the machine frame and does not cooperate in the needle motions.

I cla.im:-- 1. In a flat hosiery frame'having needle bars subdivided in each section, the central portions of which are adjustable relative to the side portions, a slide for each central portion, said slide being displaceable in the direction of the needle row and supported relative to 'the side portions, a rib disposed on said slide at a slight angle obliquely to the needle row, companion ,ribs at the foot of the central portion, said companion ribs cooperating with said first rib and adapted to adjust the central portion of the sec'- tion vertically to the needle row when said slide with the adjusting rib is displaced parallel to the needle row, a stopping device on said slide, and a counter stopping device on the sides of the central portion of the section, said counter stopping device being engaged by said rst stopping device to limit the motion of the central portion when the needles thereof are in line with those of the side portions.

2. In a at hosiery frame having needle oars subdivided in each section, the central portions of which are adjustable relative to the side porcooperating with said first rib and being adapted sojto adjust the central'portion of the'section vertically to the needle row wheri said slide with the y adjusting rib is displaced parallel to the needle row, a stopping device on said slide, and a counter stopping device on the sides of the central portion of the section, said counter stopping device being engaged by said flrst stopping device to limit the motion of the central portion when the needles thereof are in line with those of the side portions, a vspecial slide for each section, a rib for each of said slides, a driving member for each slide, a driving rod on the machine frame and displaceable parallel to the needle row, a counter driving member disposed on said driving rod within range of said rst driving member, and a spring arranged between said counter driving member and an adjusting ring of said driving rod for retaining said counter driving member and the slide driven thereby when the stop of. the slide engages the stop of the correlated sectional central portion.
